Silverlight's big brother, WPF, is at it again, this time with a replacement UI for Powershell.
PoshConsole is a more modern PowerShell Console. We aim to have a complete open source implementation of the PSHostUserInterface and PSRawHostUserInterface written in WPF and including a custom ConsoleTextBox control which could be reused for other purposes.
Of course, our PowerShell Console will also include lots of powerful features like enhanced tab-completion and keyboard navigation,
PoshConsole will also take advantage of WPF features to make it the prettiest console out there! It is already the only PowerShell Console with a Quake-like mode where the main window snaps to the top of the screen and slides down when a hotkey is pressed, and hides when it loses focus. It has separate options for setting the window's opacity, always on top, and show in taskbar ... and has fully configurable colors.
